Explanation:
Using a maps scale most of the time involves some math. Usually you'd take a distance on the map (in inches) and multiply it to whatever that maps scale is, for example 1:500. A maps scale is used to show larger distances on a map in a ratio form to show the real ground distance. Showing 10 miles on a single piece of paper would be rather difficult if there weren't a scale

Can you insert a picture of the map?
(1) Meteorological/Climate factor:
-Rainfall intensity
-Rainfall amount
-Rainfall duration
-Distribution of rainfall over the drainage basin.
(2) Phsyiographic factors (e.g. watershed)
- watershed size
-Watershed shape
-watershed slope
(3) Vegetation
- Dense vegetation leads to less run-off while sparse vegetation leads to more run-off.
(4) Urban development.
- Roads and buildings have do not allow infiltration into the soil. Water will therefore run off directly into the stream, at a very fast rate and in significant volume.
The reason oceans and rivers are barriers are because they can prevent trade, they might form natural barriers between places, and they can be difficult to navigate across. The reasons they are roadways is because they can be used to get from one place to another very fast, can help with trading, and can get you someplace you might otherwise not have been able to reaching.
